All modes of high-speed travel come with a cost to the environment.
The global warming potential of different greenhouse gases is often poorly understood, distorting which are the biggest concern.
Taxes designed to encourage a green transition can instead penalise smaller businesses and ensure they're left behind.
CO₂ will need to be removed from the atmosphere to avoid catastrophic heating. Can the process be incentivised?
An innovative method of carbon capture and storage could substantially reduce the emission of small industries while using geothermal energy to heat homes and thus replacing fossil-fuel energies.
Areas of the UK may lose their topsoil in little over a century according to new research.
Traffic congestion causes more problems than just being stuck in traffic. There are real effects on the health, quality of life and wallets of taxpayers.
Lakes are the final resting place for many of the Earth's plants – and these organic graveyards are about to get a whole lot busier.
Developers pay more tax to refurbish than demolish and rebuild – but there's a very easy fix.
Nitrogen-fixing bacteria help tropical phytoplankton absorb carbon dioxide, creating a biological pump in the oceans.
Sulfur contaminates gasoline and coal, and when these fuels are burned, sulfur dioxide is emitted, causing pollution and respiratory issues. Now there may be a new, cheaper way to remove it.
Scientists from all over the world agree that the impacts of climate change will get worse, unless action is taken now.
Carbon dioxide makes up less than one-twentieth of 1% of Earth's atmosphere. How does this relatively scarce gas control Earth's thermostat?
The United Nations is calling on world governments to step up action against climate change. Can China, the world's biggest carbon emitter, fulfill its pledges?
The Amazon will take a lifetime to recover from this year's fires – if it ever does.
Parts of Ethiopia will likely be hotter, drier, and more water stressed - with consequences for human and economic development.
What exactly is inside those red fire extinguisher canisters, and does it work better than water?
Scientists introduced credible climate change to the world in 1979, but it's taken decades for their message to sink in.
Could our best shot at stopping climate catastrophe be restoring forests on a massive scale?
The vast majority of climate scientists agree that rising CO₂ is driving climate change, yet barely 50% of the public agrees. Did scientists get the story wrong? No, as the fossil record makes clear.
